SPRAYlNG-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 511,728, dated December26, 1893.

Application filed April 7, 1893- Serial No. 469,453- (No model.)

' My invention relates to improvementsin the art of Water distribution,and has for its object the production of a nozzle capable of readyattachment to a section of hose or tubing, and when used in connectionwith an ordinary force pump, adapted to throw a solid concentratedstream, or to atomize liquids for the purpose of spraying plants,bushes, or trees to rid them of vermin common to orchards and gardensgenerally.

The invention will be hereinafter described and particularly pointed outin the claims.

In the accompanying drawings which form part of this specification,Figure 1, represents a side elevation of my invention; Fig. 2, alongitudinal sectional view of same, with valve or plug in position forthrowing asolid concentrated stream Fig. 3, a side elevation of valve orplug constituting an important feature of my invention. Figs. 4. and 5,each represents a longitudinal central section of my improved nozzletaken on line so, 0:, Fig. 1; showing also, a transverse section ofvalve or plug in its position for spraying and for throwing a solidsteam respectively, and Fig. 6, is a transverse section of valve or plugtaken on the line 3/, y, Fig. 3.

Reference being had to the drawings, in which like letters indicate likeparts wherever employed, A represents the body of my improved nozzle,preferably made of cast metal, and constructed with a globe orenlargement B at one end, the latter being perforated as shown in Fig.2, thus forming a valve seat with tapering walls a for the reception ofa valve or plug which will be hereinafter described.

The advance end of globe B is flattened as at O and recessed as at D,giving to the nozzle a flaring bell mouth discharge; while immediatelyback of this a similar though smaller recess 17 is formed in the innerwall of globe B which latter recess communicates with the former. Theopposite end of body A is provided with the usual internal screw E forconnection with a hose or pump, and communication is established betweensuch hose and the valve seat by means of a longitudinal supply channela.

F indicates a valve or plug ordinarily seated in globe B as shown, andadjustably held to its seat by means of screw 02 illustrated in Figs. 1and 2; said valve being further provided with a thumb key G as aconvenient means of turning the same axially, and a pintle, e,projecting from one side for engaging stopf on globe B and thus limitingrotation of the valve. Near its lower end, this valve is perforated by atransverse channel g, gradually reduced in size from its inlet to itsdischarge end; whileat right angles thereto is a communicatingpassagehot somewhat smaller bore for purposes that will hereinafter appear.Diametrically opposite the passage h and in the face of plug or valve Fis formed a recess or cup-shaped depression 1', adapted to register attimes with recess b-in globe B thus forming vortex chamber 1) t'as shownby Fig. 4. Opening into the depression 7. are channelsj 70, arranged indifierent planes, and consequently entering said depressiontangentially; whilethe opposite ends of each communicate with thechannel 9 from which they are supplied. The channel g, thus it will beobserved, performs a double function; namely, it not only serves tothrow a solid stream when in the position shown by Fig. 5, but when inpo sition shown by Fig. 4, serves the important function of a pressurechamber into which the water is received and held before beingdischarged. This being substantially the c0nstruction and arrangement ofmy improved nozzle, its use and operation are quite appar= ent. Vater orspraying liquid being supplied to the nozzle from a force pump, may bethoroughly disintegrated and discharged in a fine spray by manipulationof key G and its plug, until they assume the relative position in globeB shown by Fig. 4, when the liquid will be conducted from the supplytoward the discharge end of the nozzle through channels 0 and h, and bythe latter introduced into thetapering channel g. The ends of saidchannel g in this position, being closed by walls a of the valve seat,prevent passage of the liquid in these directions leaving but one meansof escape; namely, by way of tangential channels 3', 7r, into which theliquid is forced from opposite ends of the channel g. Owing to thereduced or smaller diameter of tangential channels j, k, it will beobserved that'the liquid is given an accelerated force when projectedfrom them into depression 2', and entering saidv depression in differentplanes the two streams are given a violent whirling motion in chamberi-b from whence the liquid is discharged through the flaring mouth D ofthe nozzle in the finest spray or mist If it is now desired to throw asolid concentrated stream from the same nozzle, it isonly necessary-torotate plug or valve .F until the smallerwendof channel 9 registerswithrecess 1), and its larger or opposite end with supply channel cas shownby-Figsp2tand 5'. Again, it beingvdesired to'throwacoarse spray forsprinkling purposes, or fotcleansi-ng the'several passages of the nozzlefrom sediment or foreign matter, it is only necessary to rotate Y plug-Fin" the same direction'a :few degrees furthelgwhen the channel 71 vwillregister with theadischargeopening D and the partsas- 'sume apositionthe reverse of that illustrated by-Figs; and when'it is desired to stopthe discharge of liquid from thenozzle positively, inorder to avoid thewaste :of liquid, while for-instance transferring the spraying apparatusfrom one part of an orchard or garden to anothenth'ekey G and plugFcontrolled thereby, are given a still further turn until the piningtransverse discharge passages in diiferent planes converging towardtheir outer ends, a main supply channel, and a taperingor reducedpressure channel intersecting theplug and com municating'with said"passages and channels, su'bstantially'asdescribed.
